I don't think bouncing the car off the rev limiter counts (I assume you mean running it until it hits redline in gear) as it won't allow the engine to sit north of 9K.

 

Correct. I should have been more clear. This occurred while accelerating and not while down shifting. Poor form perhaps but not even close to any damage and not recorded as an over rev.

 

Yeah this is no big deal, but ECU may still occasionally record it as an over-rev (erroneously), if it's like all previous GT3's.

 

From what I understand zone 1 doesn’t record until 9600. So bouncing off the rev limiter shouldn’t get anywhere close to a count.

 

Is that new for 992? I think Range 1 started at 9000 with 991.2, but you would still occasionally see Range 3 over-revs even with PDK cars. Same happened with Manuals that never saw a mechanical over-rev.

Here's a PDK car with Range 4 over-revs (991 GT2 RS):
Gt2rs DME report... any cause for concern? - Rennlist - Porsche Discussion Forums

 

This is my understanding with Range 1 starting at 9600 and the next at 9800 and the last at 10,000.

Guessing the first 3 weren’t worth much except to get the C&C crowd upset seeing the old range 1s.

 

It's on par with a Yogi-ism.

 

 

Out of curiosity, can an over-rev of any concern actually occur on hard acceleration in a gear - ie coming out of slow 2nd turn, slow to upshift and rev limiter is slow to intervene and catch it on full throttle acceleration?

Anyone ever have their cars ignition shut off in the above scenario?

Asking for a friend ...

 

No concern. The electronics that fire the engine (fuel and spark) are the same ones that control the rev limit. It's not possible to out-drive them (rev limiter is extremely effective - electricity is fast )...

 

If you have a serious over-rev you will know it. You will either see smoke and hear a bang, or warning lights will pop up on the dash. That said, not all over-revs cause actual damage or lead to damage down the line. I had a Range 6 over-rev in my previous car and it was fine. Was accelerating in 3rd, went to shift to 4th and tried to shift super fast, but hit 2nd gear gate by accident. Dumb mistake. Immediately caught it by hitting clutch. Car threw some codes. Had engine checked, scoped, compression/leak-down test, inspect cylinders/valves, etc. No damage. Car still tested fine. In fact, it tested better than Porsche's tolerance/spec.

BTW, I don't think Range 6 is over 10,000 RPM.

 

Was it a 991 GT3? Different models have different ranges.

 

Yeah. 991.2. It's different on the 992?

 

That is what is being reported. 991.2 Range 1 was 9,000-9200 (I think - I know it started at 9000). Apparently 992 has Range 1 starting at 9600 rpm to reduce erroneous and irrelevant reports.

I'm pretty sure Range 6 on 991.2 GT3 is in excess of 10k rpm (but I'm not the one that originally made that claim). I think each range is at least 200 rpm wide beginning at 9000.

 

Ah yes you're right, just checked old DME report and shows engine speed of 10,085. Total of 6 ignition cycles. I wonder what that equates to in seconds. Can anybody do the math? Something with RPM to per second and each ignition cycle is what, etc.?
